In good news for veggies that get little of the limelight, watercress, chinese cabbage and chard tops the list of foods that will give you the most nutrients per bite, suggests a new study. And surprisingly, you’ll find some of the most talked about plant foods in health – such as blueberries – didn’t even make the list.

Chard, ranking #3 on the “powerhouse” list

The study, published in Preventing Chronic Disease, sought to rank how 47 fruits and vegetables stack up as nutrient “powerhouses.” Eating more of these fruits and veggies, notes the study, is one approach linked to reduced risk of chronic diseases, which includes cancer.

“This is a great opportunity to learn about some fruits and vegetables we’re not as familiar with, but for cancer prevention and overall health — ALL fruits and vegetables are powerhouses,” says AICR Associate Director of Nutrition Programs Alice Bender, MS, RDN. “AICR research — and the government guidelines — say what’s most important when it comes to eating fruits and vegetables: eat more, eat a variety.”
